These samples showcase different architectural approaches to developing Android apps. In its different branches you'll find the same app (a TODO app) implemented with small differences.

In this branch you'll find:

• User Interface built withJetpack Compose
• A single-activity architecture, usingNavigation Compose.
• A presentation layer that contains a Compose screen (View) and aViewModel per screen (or feature).
• Reactive UIs usingFlow andcoroutines for asynchronous operations.
• Adata layer with a repository and two data sources (local using Room and a fake remote).
• Twoproduct flavors,mock andprod,to ease development and testing.
• A collection of unit, integration and e2etests, including "shared" tests that can be run on emulator/device.
• Dependency injection usingHilt.

The app in this project aims to be simple enough that you can understand it quickly, but complex enough to showcase difficult design decisions and testing scenarios. For more information, see theapp's specification.

• A template. Check out theArchitecture Templates instead.
• A UI/Material Design sample. The interface of the app is deliberately kept simple to focus on architecture. Check out theCompose Samples instead.
• A real production app with network access, user authentication, etc. Check out theNow in Android app instead.

• Intermediate developers and beginners looking for a way to structure their app in a testable and maintainable way.
• Advanced developers looking for quick reference.

To open one of the samples in Android Studio, begin by checking out one of the sample branches, and then open the root directory in Android Studio. The following series of steps illustrate how to open the sample.

Clone the repository:

git clone git@github.com:android/architecture-samples.git

Finally open thearchitecture-samples/ directory in Android Studio.
